Fine but I ain't showing my work completely.
The sum of all ext. angles of a polygon = 360.
So, you make this formula and solve for x.
360 = 49 + (3x+30) + (14x+6) + (6x-3) + (4x+8)
360 = 49 + 27x + 30 + 6 -3 + 8
360 = 90 + 27x
270 = 27x
/27 /27
10 = x
Now substitute for angle A, which is (6x-3)
6x-3
6(10)-3
60-3
57
Therefore, angle A is 57 degrees.
The highest power is 2.
Explanation:
Because x has a maximum power of 2, there will be 2 answers. if it were 3, there could be up to 3 answers, etc.
While solving this problem, you gather all terms on one side so the equation looks like
x
2
−
81
+
17
=
0
x
2
−
64
=
0
then factor
(
x
−
8
)
(
x
+
8
)
=
0
then, because any number times 0 equals 0, we know that one of the two parts in the parenthesis must be equal to 0, so
x
−
8
=
0
or
x
+
8
=
0
and so the two answers
x
=
8
,
−
8
come to be.
25 is your answer , thanks
Step-by-step explanation:
Since d is an decimal, the higher the power of d, the smaller the value.
